(Photopea is a free browser based photo editor and illustration tool capable of rendering and exporting images and basic animations. The interface works just like Adobe Photoshop but with limited functionality to make it viable for use in the browser.  It is completely free to use making it a budget friendly way to learn digital art, you do not need to create an account or subscribe. Photopea can run on any device (desktop, laptop, tablet, phone or any other computer), but for the best comfort, we recommend having a big screen, a precise pointing device (a mouse or a stylus) and a keyboard. Photopea runs completely in your device, just like Sketch or Photoshop do. It is compatible for both Mac and Windows. ) 

Students are welcomed to use their own familiar digital art programs. For students using the free resource Photopea, no sign-up or registration is required. Free to use on all devices.
